The “text me if I'm blocking you” sticker, without your number

The classic move, a phone number on paper tucked under the wiper, asks you to publish your personal cell to every passerby, forever. A HeyTextMe sticker on your window does the same job privately.

The blocked-driveway problem

Tight streets, shared driveways, double-parked deliveries: sometimes a stranger legitimately needs to reach you about your car right now. Every existing answer is bad. A written number can be photographed once and spam-called forever. A note says nothing when you're not there. And a towed car ruins two people's day.

What happens instead

Why not just an SMS QR code?

Plenty of generators will make a QR that opens the scanner's Messages app, with your real number pre-filled. That's the same exposure as the paper note, laminated. The whole comparison is at vs. SMS QR codes, but the short version: a code that contains your number is your number.

Parking-specific details that matter

• It works when you're far from the car. The push reaches you at your desk; a knocked window doesn't.
• Sold the car? Pause the sticker. A written number on a sold car keeps ringing for years.
• Late-night lot anxiety: messages come to the relay, not your number, so no 2am calls from someone who photographed your windshield.

Also good on motorcycles and scooters (no windshield to tuck a note under), and next to the lost & found sticker on anything that rolls.
